Is there a good user interface for authoring Oracle SQL Loader control files? PL/SQL Developer includes a "Text Importer" feature (that reminds one of the Excel import wizard) to import text files into tables, but uses a proprietary format instead of the SQL Loader format. Something like this for the SQL Loader format would be quite helpful.
TOAD has an interface to do SQL*Loads, it can generate the control files too...

The TOAD answer is probably the best at present. However, in trying out the TOAD SQL Loader wizard, I was disappointed at the level of usability. It assumed that I had a pre-existing table to load the data into. I was looking for something that would let me first
locate columns in the fixed-width input file, then
analyze the columns for candidate names and data types, then
generate a table and control file for loading the data
Since I couldn't find anything that would adequately meet my needs, I created a utility for the purpose. The utility is somewhat custom to my specific needs (fixed-width file format, headers on top, dashed divider separating headers from data, white space between columns) and only supports the SQL Loader features that I required. If I have opportunity to flesh it out to something more universally usable, I'd be happy to post it for the community.

I am using both Oracle Forms version 11g and 12c.
Is it possible to find a table for e.g table1 used in the Oracle Forms application screens including LOV's without opening each FMB individually and searching in it.
Totally there are around 50-75 FMBs in the application.
Thanks
While Forms was a new software product, back then in its 3.0 version (or even lower), you could choose whether you'll keep the form source
in the database or
in that case, you could have written a query which selects data from the data dictionary and - hopefully - extract tables' names
in file system
file extension was .INP (not .FMB) and it was a textual file; it means that you could even create a form using text editor! Nobody probably did that, but hey - you could have done it.
.FMB is no longer textual file. Yes, you can open it it a text editor (such as Notepad++) and search for e.g. FROM (because any table used in form's PL/SQL units or LoVs is part of a SELECT statement which requires the FROM keyword) and get something like this:
Yes, you'll get "duplicates" if any table is referenced more than once.
Another option is to write a program which will parse the .FMB file and extract tables' names (I can't help with that, though).
i've a simple question, but huge issue for me.
i have need to recover the data which is in a encrypted btrieve file, for migration purpose, but i can't access to the record structure.
Someone knowns a technique for that? or opensource program?
Thanks for any help or direction to go.
By "encrypted," do you mean it has an owner name or do you mean that when you open it in a text editor, it looks strange?
Btrieve data files require the Btrieve / Pervasive PSQL engine in order to be read. Once you have the engine, you can open it and read it. You'll still need to know the record layout (or guess) in order to extract meaningful data from it. Btrieve files do not store field metadata so any Btrieve tool will only see the record as a collection of bytes.
If you know the record structure, you can create a table definition using DDF Builder or the Pervasive Control Center, and then access the table using ODBC (or JDBC, ADO.NET, PDAC, ActiveX, or OLEDB) and extract the data using your favorite tool.
We have a portal written in php/mysql and an enterprise application based on Java EE and Oracle. Recently we found out that a certain Unicode character (0643 to be precise) is invalid (due to improper data entry by end users) in text columns and must be changed to another character (06A9).
In MySQL I simply changed the export file using a text editor's find and replace tool. But in oracle, the dmp file is a binary file and i have no idea about how to edit the dmp file.
How can I change the invalid character?
Is there an alternative to iterating through all text columns in all tables?
(I have saved that as a last resort!)
Editing an Oracle dump file may be possible but isn't practical; even if you could get in and change something you'd risk corrupting it, and I doubt Oracle support would be impressed. (See this AskTom question for example).
If you're using data pump and you know which column(s) the data is in you might be able to use the REMAP_DATA parameter to change it on the fly, or the QUERY parameter to skip the data, but it doesn't sound like you're in that situation. You could potentially add temporary constraints to the relevant column(s) to block the value, so import would reject (and log) the affected rows, but that's painful and messy.
If you do have to check all columns on all tables, this link may be helpful.
How can I retrieve data (using sql) from Excel to a table in Oracle database. I am using dbsaint.
Instead of DBSAINT, which developer tool should I use for this purpose?
The easiest way to do this is to export the data from Excel into a CSV file. Then use an external table to insert the data into your database table.
Exporting the CSV file can be as simple as "Save as ...". But watch out if your data contains commas. In that case you will need to ensure that the fields are delimited safely and/or that the separator is some other character which doesn't appear in your data: a set of characters like |~| (pipe tilde pipe) would work. Find out more.
External tables were introduced in Oracle 9i. They are just like normal heap tables except their data is held in external OS files rather than inside the database. They are created using DDL statements and we can run SELECTs against them (they are read only). Find out more.
Some additional DB infrastructure is required - the CSV files need to reside in an OS directory which is defined as an Oracle dictionary object. However, if this is a task you're going to be doing on a regular basis then the effort is very worthwhile. Find out more.
I don't know much about DbSaint; it's some kind of database IDE like TOAD or SQL Developer but focused at the cheap'n'cheerful end of the market. It probably doesn't support this exact activity, especially exporting to CSV from Excel.
I want to load data into text file that is generated after executing "views" in Oracle?How can I achieve this in oracle using UNIX.for example-
I want the same in Oracle on unix box.Please help me out as it alredy cosume lots of time.
your early response is highly appreciated!!
As Thomas asked, we need to know what you are doing with the "flat file". For example, if you're loading it into spreadsheet or doing some other processing that expects a defined format, then you need to use SQL*Plus and spool to a file. If you're looking to save a table (data + table definition) for moving it to another Oracle database then EXP/IMP is the tool to use.
We generally describe the data retrieval process as "selecting" from a table/view, not "executing" a table/view.
If you have access to directories on the database server, and authority to create "Directory" objects in Oracle, then you have lots of options.
For example, you can use the UTL_FILE package (part of the PL/SQL built-ins) to read or write files at the operating system level.
Or use the "external table" functionality to define objects that look like single tables to Oracle but are actually flat files at the OS level. Well documented in the Oracle docs.
Also, for one-time tasks, most of the tools for working SQL and PL/SQL provide facilities for moving data to and from the database. In the Windows environment, Toad's good at that. So is Oracle's free SQLDeveloper, which runs on many platforms. You wouldn't want to use those for a process that runs every day, but they're fine for single moves. I've generally found these easier to use than SQLPlus spooling, but that's a primitive version of the same functionality.
As stated by others, we need to know a bit more about what you're trying to do.
